@jasonnix there is having something faster and there is something that’s going to be reliable. I’d rather compromise on faster backup speed and have the designed backup system.
I’m not saying that Veeam isn’t going to be reliable but what I am going to say is that you are at more risk of backups not being reliable and you are going to have to consult Veeam if you need help resolving a issue, where with XO you are not going to have any problems as it’s designed to work.
Not only that you need to think about extra licensing too.
If this is a Production environment I would go with the XCP-ng and XO because if something goes wrong you are going to be a laughing stock to the company it will be embarrassing. If it’s a homelab then it doesn’t really matter if it breaks.
